Tamixalus calcadensis

The Kalakad gliding frog, also called the Kalakkad tree frog, is a frog in the family Rhacophoridae endemic to the southern Western Ghats in Kerala and Tamil Nadu. The Wikipedia account sits under the name Rhacophorus calcadensis; its name refers to its type locality, the town of Kalakkad in Tamil Nadu. It is pale greenish-brown with mottling on the flanks and a fawn to pale green underside, with webbing of similar colour between the fingers and toes, skin flaps on the fore and hind limbs, and a spur on each hind limb (Wikipedia, general species account).

It is seen high in the forest canopy, over 30 m up, by day. It breeds before or after the monsoon by descending to shallow pools or slow-flowing streams, where groups of four or five males call around the females and build foam nests on vegetation hanging over the water, smaller than those of Rhacophorus malabaricus. It is threatened by habitat loss (Wikipedia, general species account).
